Example Input: Question: How long did Weichardt's group stay in existence? Passage:Nazism found an audience in the country, with pro-Nazi elements organised by Louis Weichardt in 1932 under the name South African Gentile National Socialist Movement, a group that soon became known as the Greyshirts. Although the group enjoyed some support and continued after the Second World War they never became sufficiently important for the government to take action against them. The other main fascist group was the Ossewabrandwag (OB), founded in 1939, a group also inspired by Adolf Hitler. The two differed however as the Greyshirts emphasised Aryan race rhetoric and so organised amongst the various white immigrant communities whilst the OB were specifically for Afrikaner only. A third, more minor group, the New Order, emerged in 1940 under the leadership of former cabinet minister Oswald Pirow. After the Second World War Pirow became an important figure in neo-fascism, working closely with Oswald Mosley, Nation Europa and A. F. X. Baron. Nazi Germany sought to encourage such activity with former Olympic boxer Robey Leibbrandt active as an agent for the Abwehr during the war. The Nazi Party itself also organised until it was outlawed in 1936.

Example Input: Question: Which team did Ferby lose to in the semi-finals of the 2001 Worlds? Passage:In 1999, Rycroft left the team to play with Ferbey's main rival, Kevin Martin. Rycroft was replaced by Marcel Rocque. The Ferbey Four that would dominate the Brier for the next few years was complete. Ferbey made his return to the Alberta provincials in 1999. While they didn't win, they did return in 2001 with a bang. They went on to winning not only the Alberta championship, but the 2001 Nokia Brier as well beating Kerry Burtnyk of Manitoba 8–4 in the final. This sent the team to the 2001 Worlds where they lost both their semi-final game and the bronze medal game, which they gave up to Pål Trulsen of Norway. In 2002, Ferbey won his fourth Brier, the 2002 Nokia Brier, which was his team's 2nd. They beat John Morris 9–4 in the final. This time, at the 2002 Worlds in Bismarck, North Dakota his team won the championship, beating the same Pål Trulsen, 10–5. Ferbey and his team would return to the Brier, at the 2003 Nokia Brier in Halifax, Nova Scotia. In the finals, they beat the home-town favourites Mark Dacey 8–4 in the finals. At the 2003 Ford World Curling Championship, his team won their 2nd world title, beating Ralph Stöckli of Switzerland 10–6 in the finals. The 2004 Nokia Brier was a blip on his team's record. After returning to the Brier for the fourth straight year, an unprecedented feat especially considering the great number of good teams in Alberta, his team would bow out in the final. After a 10–1 round-robin record, Ferbey and his team lost out to the same team they beat the previous year, Mark Dacey of Nova Scotia, in a 10–9 game where Ferbey's team surrendered a lead. However, Team Ferbey did not give up, and their reign would not be over. In 2005, the once again won the Alberta championships, and once again won the 2005 Canadian championships. This set a record, as his team became the first to win 4 championships as a team. The final was against Nova Scotia again, albeit a different team, that of Shawn Adams. In another close game, team Ferbey pulled it out and won 5–4 in the final. His trip to the 2005 Men's Ford World Curling Championships were marked with struggles, as the team finished the round-robin with three losses – tied for first with five other teams. After having a 4–3 record, Ferbey mounted eight straight wins to win the championship over David Murdoch of Scotland in a convincing 11–4 victory. Additionally, the Ferbey rink was the first team in history to score five on any single end in the world finals – and they managed this feat twice at the 2005 Ford World Curling Championships.

Example Input: Question: Did the same person finish ahead of Bekele in both of the races he began in Europe with in 2018? Passage:He began 2018 in Europe with third at the Czech Indoor Gala and a runner-up finish at the Cinque Mulini. A 5000 m win at the Ethiopian U20 Championships and a personal best of 13:04.63 minutes to win at the Meeting Iberoamericano de Atletismo saw him enter the 2018 IAAF World U20 Championships saw him enter the competition as the second fastest runner after training mate Selemon Barega. He was beaten by the heat, however, and finished fifth in the 5000 m. He made his IAAF Diamond League debut that year, placing seventh at Athletissima. He closed the year with third place at the Great Ethiopian Run. At the start of 2019 he continued to show his strength over distance with second place at the Giro Media Blenio 10K. Turning to the track, he won the Ethiopian national title, was fifth at the Shanghai Golden Grand Prix, then had his first Diamond League victory by winning the 5000 m at the Golden Gala, beating his partner Selemon Barega. He was third at that year's Athletissima and placed fourth at the Diamond League final at the Weltklasse Zürich.
